Fig. 2 is a longituquently preventing any escape of gas or oil.

11 to establish communication between plug the ower portion ofthe bore 2 and one of the through the sides of the bore 21 it is evident that a means is set up whereby the gas or oil can be conducted from the well through the port 20 while the supporting cable 9 extends down port 2. The bore 21terminates ininteriorly threaded nipples 22 and which can be 'connected to suitable pipes, not shown, for conductin the oil or gas to suitable reservoirs or tans.

What I claim is: 'A valved plug for oil' well-casing comprising a housing formed with a tapering seat extending transversely therethrough and angularly disposed with respect to the well casing, said housing further provided with a vertically extending and a horizontally extending bore, each of said bores formed of a pair of branches, said seat communicating with said bores, said vertical .bore constitutin a passage for a drill supporting cablev which i against said 'seat and provided with a passage extends through the housing, a plug mounted' for establishing vcommunication between the upper and lowerbranches of thevertical 'away portion estab bore, said plug further having its periphery cut away for establishing communication between one of the branches of the horizontally extending bore and the lowerbraneh of the vertical bore when said p lug is in its nor- 1 mal position, saidplug further adapted when shifted from normal )esition to have said cut lish communication between the other branch of the horizontally extending bore and the lower branch of the vertically extending bore and'wh'en so shifted cutting ofi communication between the two branches of the vertical bore,'said plug projecting at both ends from said housing,
